Is there a standard procedure or set of test tones for calibrating (level-matching) the sub to the two speakers? I'm beginning to enjoy my LSi7s with a new DSW micoPRO 2000. I decided to put on one of my favorites - Pink Floyd's The Final Cut. When it got to When the Tigers Broke Free, the pounding thuds at the beginning of the track were shaking the crap out of everything within three feet of the sub! I know I could just go by ear, but I really would like to make this 2.1 bookshelves and sub rig sound like 2.0 towers, if you know what I mean.
